Abstract
In recent years, fluorescent dyes have received more and more attention in the field of packaging anti-counterfeiting due to their good concealment, bright colors and convenient inspection. At the same time, research on new fluorescent inkjet inks based on the interaction between biopolymer DNA and fluorescent dyes has attracted wide attention. In this paper, the Eu(TTA)3(H2O)2 complex was synthesized and the luminescence property was analyzed. It is found that when the Eu(TTA)3(H2O)2 content was 0.7% and the ratio of DNA-Lau to Eu(TTA)3(H2O)2 was 1:20, the luminescent dye had the highest luminescence intensity. The fluorescent ink was prepared as a pigment, the results showed that the resin content was 15%, the mixing ratio of propylene glycol methyl ether to propylene glycol methyl ether propionate was 0.61:0.39, and the luminous intensity, surface tension and viscosity of the fluorescent ink were optimized, which laid a solid foundation for the development of new fluorescent inkjet inks.
